Specification of Letters Patent.

Patented May 16, 1916..

T0 all whom 'it may concern:

Be it known that I, HARRY J. HIOK, a citizen of 4the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Locks, of which the following is a specification.

The invention relates to locks for reproof cases or cabinets, and the object of the improvement-is'to place all the locking parts within the case to protectfthe saine from fire or other elements; to arrange the saine for locking without the use of a key, while requiring a ,keyto unlock them; to construct the locking and operating elements without any open holes or apertures in or through the wall of the case to permit the entrance of tire or other elements into the case; and finally, to construct the locking and operating parts so that they cannot be damaged, destroyed or unlocked by the shocks or strains resulting from a falling of the case, or from a falling of other Objects upon the case.

The objects of the invention, thus briefly set forth, are attained by the preferred embodiment thereof which is illustrated in the accompanying drawing, forming part hereof, in which Figure 1 is an inside perspective view of the improved lock Showing a fragmentary section of adjoining walls of a case locked together; Fig. 2, a section of the same longitudinally of the locking and operating elements; Fig. 3, an inside perspective view of the lock in open or unlocked relation, showing the case walls in broken lines; Fig. 4, a detached perspective view of the slotted key cylinder; Fig. 5a front elevation of the stem head and the handles; and Fig. 6, a detached perspective view of the unlocking key.

Similar numerals refer to similar parts throughout the drawings.

The lock is composed of the operating elements, which include the stern 1, the handles 2, the key cylinder 3, and the key 4; and the locking elements, which include the locking plate 5, the latch 6, the keeper 7 and the locking post 8.

The stein 1 of the lock is provided with the journal 9 on its inner end extending into and through the corresponding bearing 10 provided in the wall 11 of the case or cabinet; and when this wall is made of spaced surface plates 12 with intervening fire resisting material 13, as shown, the journal bearing 10 is preferably made in the bushing 14E secured between the face plates 12 of the wall, which face plates are provided with apertures corresponding to the journal bearing in the bushing.

The annular shoulder 15 is preferably provided on the stem of the lock in abutment with the outer face of the wall, and on the head 16 of the stem are 'secured two or more radial handles 2 which can be conveniently 'grasped by the hand of the op` erator for manipulating the lock and opening and closing the case. j

The stem 1 is also provided with the axial bore 17 which extends from the inner end of the stem outward to a point within the outer end thereof, thus leaving a solid front face 1S for the outer end or head of the stem; excepting that the slot 19 is provided therein for the entrance of the wings 2O of the key t, which slot is preferably provided with a central enlargement 21 for the shank 22 of the key.

The key cylinder 3 is fitted neatly in the bore of the stem and is provided with the diametric slot 23 with the central enlargement 24 in its outer end for receiving the wings 20 and the shank 22 of the key; and with the diametric tongue 25 protruding inward beyond the inner end of the stem.

The locking plate or bolt 5 is provided with the aperture 26 intermediate its ends, by means of which the plate is secured crosswise on the endl of the stem 1 as by screwing and keying thereon, the parts being preferably so arranged that the locking plate will be contiguous or adjacent to the inner face of the wall of the case.

The hook 27 is provided on one end of the locking plate and the post 8 is provided on the inner side of the wall 11a of the case to which the wall 11 is designed to be locked, and it is evident that by rotating the locking plate by means of the stem 1 and handles 2, the hook A7 may be brought into en gagement with the post 8 for clamping and locking the case walls together, as shown in Figs. 1 and 2. The latch 6 is mounted on the other end of the locking plate, preferably on the inner side thereof, by means of thescrews Or rivets 28 having their shanks extending through the longitudinal slots :'29 provided in the latch and their heads engaging the outer sides of the rims of these slots, thereby permitting a limited longitudinal movement of the latch upon the locking plate.

The keeper 7 is secured to the wall 11 of the case adjacent to the latched end of the locking plate when the hooked end thereof is in engagement with the locking post 8; and this keeper is provided With the notch 30 for receiving and engaging the free end 31 of the latch when the locking hook is engaged with the locking post. The free end 31 of the latch 6 is preferably bent at right angles to the latch over the adjacent end of the locking plate, and the compression spring 32 is provided between the bent end -of the latch and the adjacent end of the locking plate, Which spring acts to move the free end of the latch radially from stem 1 of the lock. One side 33 of the notch 30 in the keeper 7 extends farther to- Ward the stem 1 of the lock than the other side 34: of the notch, and on the same side of the notch the keeper 7 is extended and curved to form the abutment 35 for stopping the locking plate 5, as shown in Fig. l3, When the locking plate is rotated a quarter turn from the position in which its hooked end is engaged with the locking post 8.

The parts are constructed and arranged so that when the locking plate is rotated from its disengaged position, shown in Fig. 3, to- Ward and into its engaged position, shown in Fig. 1, the free end 31 of the latch will rst impinge the edge 36 of the keeper adjacent to the notch 30, and after sliding along this edge will enter and be engaged in the notch 30 by the action of the spring 32; it being evident that the extension 33 of the farther' side of the notch serves to stop and prevent the end 31 of the latch from rotating beyond the notch.

The cam orifice 37 is provided in the latch 6, into which orifice the diametric tongue 25 on the end of the key cylinder extends and operates to release the latch from the keeper. One end 38 of this orifice is squared and is positioned so that when the tongue 25 is rotated to be transverse, as shown in Figs. 1 and 2, the squared end of the orifice abuts the flat side of the tongue when the end of the latch is engaged in the notch of the keeper. The other end 39 of the orifice is suitably extended, and may be rounded if desired, so that When the tongue 25 on the end of the key cylinder is rotated to be longitudinal of the latch, as shown in Fig. 3, one edge of the tongue Will operate against the squared end of the orifice to move the latch against the action of the spring 32 and disengage its free end 31 from the shallow side 34 of the notch in the keeper; and this edge of the tongue is suitably squared so that the resisting action of the spring serves to hold the tongue in longitudinal position against an accidental rotation of the key cylinder.

The key slot 19 in the head of the stem is alined With the length of the locking plate, and the latch; and the key slot 23 in the outer end of the key cylinder is transversely positioned With reference to the tongue 25 on the other end thereof. By this arrangement of the parts it is evident that When the hook on the locking plate is engaged With the locking post, and the latch is engaged with the keeper, as shown in Fig. 1, the Wings of the key may be inserted through the slot 19 in the stem head into the slot 24 in the outer end of the key cylinder, Whereupon a quarter turn of the key and cylinder serves to disengage the latch from the keeper, and a subsequent turning of the handles 2 serves to disengage the hook on the locking plate from the locking post, to bring the parts into the disengaged position shown in Fig. 3. In this relation of the parts the key can only be Withdrawn by giving it a quarter turn to alineits Wings with the slot 19 in the head of the stem; which quarter turn rotates the tongue on the inner end of the key cylinder to be transverse the latch, and in this position of the tongue the spring 32 throws the latch eudwise to bring the squared end of the orifice 37 against the flat side of the tongue, so that the latch will automatically engage With the keeper slot When the stem is rotated to engage the locking hook With the locking stem. The action of the spring 32 serves to hold the latch abutment against the flat side of the cylinder tongue, and prevents an accidental turning of the same When the key is Withdrawn; thereby maintaining the latch in locking position, and the cylinder slot in alinement With the stem slot for a reinsertion of the key.
